It is heavy

You can say that again. The specs list it as 5 lbs 4 oz (2.4kg)!!

I have never owned a pack that heavy, either external or internal frame, and I've been backpacking for more than 40 years. I cannot fathom the need for a pack to weigh that much to do the job of carrying gear, clothes and food. What's even more astounding to me is that its capacity is a fairly pedestrian 3966 cu-in (65 liters).

I admit that I know nothing else about this pack other than the specs I have just mentioned above, but those two specs alone would put me off it, whether it was in 1970 or 2014. Even before discovering the price was $295.

But, if that is your cup of tea, who am I to say you are wrong to want it?
